This study aimed at finding appropriate interval of ranged speed hump from the viewpoint of noise and vibration as well as effect of speed reduction through two experimental installation. In the experiment, "sinusoidal mobile humps" were used. In the first experiment, conducted in Kokubunji city, it was found that 60m-inerval can reduce speed less than 30km/h in all over the road section. However, residents complained the noise caused by re-acceleration. In the second experiment conducted in Bunkyo-ward, Tokyo, the intervals between humps reduced to 20m to make drivers to "give up" to re-accelerate. Judging from the result of questionnaire survey and noise observation, it was successful.

Nowadays, various signalized intersections with bicycle lanes designs are available for implementation. However, no safety comparisons have been made between these various designs. Therefore, it is necessary to compare the various designs available. In this study, intersection designs from Western countries are investigated to determine the safety measures available. Then the safety and comfort are compared with left-hooks being focused. Five patterns were selected including (1) Mixed traffic with left-turning motorist; (2) Left-turn in the intersection for motorist; (3) Bicycle signal; (4) Advanced stop lines for bicycles; and (5) Bicycle box. The five intersection patterns were prepared at an experiment site, and human subjects consisting bicyclist and motorist were traveled on the specified route freely. Questionnaire surveys and video observations were used for data analyses. The results show that (1) Mixed traffic with left-turning motorist is the safest and (3) Bicycle signal is the most comfortable intersection design.
